IND HALL IND HALL IND HALL DATA SHEET D-330 KBET-240D Frequency to Analog Tachometer and Follower Converts a Pulse Input Signal Into Individual Isolated Tachometer Feedback and Follower Output Signals ® P/N 9469 STANDARD FEATURES DESCRIPTION • Sensor Type: Open Collector (Hall, Magnetic, Inductive, Opto) and Two-Wire Inductive The KBET-240D is designed to accept a pulse input, which is produced by most “open collector” (Hall, • AC Line Voltage 115 or 230 VAC magnetic, inductive and opto) or 2-wire inductive pickups, • LED “Pulse” Indicator (Red) and to create two independent isolated output signals. • LED “Power On” Indicator (Green) The Tachometer Output is normally used for tachometer feedback. The Follower Output is used to drive a second TRIMPOT ADJUSTMENTS control in a master/slave system. If tachometer feedback • Tachometer Output (TACH) is not required on the master motor, the Tachometer Output can be used to drive an additional slave. • Follower Minimum Output (MIN) Two LED indicators are incorporated into the KBET • Follower Maximum Output (MAX) circuitry. The “Power On” LED is used to indicate that the SPECIFICATIONS unit has AC power, and the “Pulse” LED is used as a diagnostic to verify the presence of an encoder input. AC Line Input Voltage ...... 115/230 ± 15% VAC – 50/60Hz Jumper selections allow for setting the AC input Tachometer Output Voltage Range (VDC) .............. 0 – 17 voltage (115/230 VAC) and the sensor type. The KBET is Tachometer Output Trimpot Range factory calibrated to 7V/1000 RPM (60 pulses/rev pickup) for the Tachometer Output and 10 VDC per 1800 (Millivolts Per Pulses/Sec.) ................................ 3 – 8 RPM for the Follower Output. Multiturn trimpots are Tachometer Output Trimpot Range provided to tailor the Tachometer and Follower Outputs (Volts at 1000 RPM and 60 Pulses/Sec .... 3.5 – 10.0 for specific applications.
